REVERSING APPARATUS FOR DYE-VATS, 84C.

SPECIFICATION forming part of Letters Patent No. 680,553, dated August13, 1901.

Application filed May 15, 1901. Serial No. 60,339. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOHN T. TRAVIS, a citizen of the United States,residing at Paterson, in the county of Passaic and State of New .Iersey,have invented certain new and useful Improvements in Reversing Apparatusfor Dye- Vats and other Machines; and I do declare thefollowin g to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The invention relates to reversing apparatus for dye-vats and othermachines.

The object of the invention is to provide apparatus of this characterwhich shall be simple of construction, durable in use, comparativelyinexpensive of production, and by means of which the fabric undertreatment will be automatically passed back and forth through the dyeliquor from a drum mounted at one end of the vat to a drum mounted atthe opposite end, thus dispensing with the employment of an operator foreach machine to reverse the direction of movement of the cloth andmaking it possible for one operator to attend to a large number ofmachines at the same time, as his attention is only required in stoppingand starting the machine.

With this and other objects in view the invention consists of certainnovel features of construction, combination, and arrangement of parts,which will be hereinafter more fully described, and particularly pointedout in the appended claims.

In the accompanying drawings, Figure 1 is alongitudinal vertical sectionthrough a dyevat, taken through the cloth-drums and cloth and showing inside elevation my improved reversing mechanism for changing thedirection of movement of the cloth within said vat. Fig. 2 is a top planView of my reversing mechanism, a portion of a fragment of the web ofcloth being shown and of the cloth-attaching strip and the trip foroperating the reversing-levers. Fig. 3 is a longitudinal sectional viewthrough the drive-shaft and parts thereon mounted, and Fig. 4 is adetail perspective view of one of the loosely-mounted clutch members andits drive-gear.

Referring to the drawings, 1 denotes bearings, 2 the drive-shaft,havingits ends mounted in said bearings and provided near one end with afixed pulley 4 and an idle pulley 3, the former of which is adapted tobe driven by a belt from any suitable source of powersupply and thelatter of which is adapted to receive the belt when it is desired tostop the machine. 5 and 6 denote two bevel gear wheels loosely mountedupon said shaft, and 7 and 8 denote two clutch members fixed to turn inunison with the gear-wheels 6 and 5, respectively, and are preferablycast integral with said gear-wheels, and each is provided on its innerface with an annular groove having a cross-stop 9. Each gear-wheel, withits clutch member, is confined on said shaft against longitudinalmovement thereon by a fixed collar 10 and a clutch member 11, each ofwhich is fixed to said shaft. The clutch member 11 is preferably in theform of a hub and is provided with a longitudinal opening or chamber 12,within which is located a rod 13, upon which is placed a coil-spring14:, which is confined between the forward wall of the chamber and anannular shoulder 16, secured to said rod. A cap-plate 17 is secured tothe hub to limit the forward throw or movement of the rod, the inner endof which is held normally projected through an aperture 18 in thecap-plate by the action of the spring.

19 denotes a rock-shaft journaled in suitable bearings 20 and providedwith fixed shipper-lugs 21.

22 denotes a shipper-head mounted loosely upon the drive-shaft betweensaid shipperlugs and provided at its ends with laterallyprojectingflanges 23, which are arranged within the path of movement of theshipperlugs and are adapted to be engaged thereby in the rocking of theshaft 19 to move the shipper-head longitudinally upon the driveshaft tomove the spring-actuated rods.

When. the shipper-lug is in the position shown in dotted lines in Fig. 2and full lines in Fig. 3, the spring-actuated lug carried by the clutchmember 11 has its outer end projecting into the groove of the clutchmember 8, and when it comes in contact with the stop in said groove theclutch member 8 and gearwheel 5 are caused to turn in unison with theclutch member 11 and drive-shaft. When in this position, the point orprojecting end of the shipper-lug is in engagement with the stop 24,which prevents the shipper-lug from being moved too far downwardly andout of engagement with the flange.

25 denotes a rock-drum fixed to the shaft 19 and provided with twogrooves 26.

27 denotes crossed reversing-levers, each having its lower end pivotedtolugs 28, projecting inwardly from the sides of the dyevat 29, andtheir upper ends connected to the lower ends of chains 30, the upperends of whichrare wound around the rock-drum in opposite directions andare fixed thereto, said chains being supported or guided intermediatetheir ends by pulleys 31, mounted in brackets 32.

33 denotes posts or standards secured to the ends of the dye-vat. 34Edenotes shafts journaled in the upper ends of said standards 33 and inthe upper ends of standards 35. Fixed to said shafts 34 are bevelgearwheels 36, which are in mesh with the bevel gear-wheels 5 and 6 andreceive motion therefrom.

37 denotes cloth-drums fixed to the shafts 34, and 38 denotescloth-attaching strips fixed to said drums and of suitable length toreach to the dye liquor in said vat.

39 denotes a strip of cloth connected at each end to theattaching-strips, and 40 denotes trips carried by the attaching-stripsfor actuating the reversing-levers.

41 denotes a roller journaled in the lower end of the tank, about whichthe cloth strip rolls, and 42 denotes slats arranged across the tank forpreventing the cloth from creasing as it is wound on the cloth-drums.

In operation as the cloth is drawn through to the other a trip willengage one of the reversing-levers and depress the same, thus rockingthe shaft 19, which movement shifts the shipper-head 22 and allows thespringactuated rod with which it has been in engagement to free itselffrom one of the loose clutch members and at the same time throw saidshipper-head toward the other end of the shaft and force the oppositespring-actuated pin outwardly into engagement with the other looseclutch member and cause said clutch member to rotate with the mainshaft, and as this latter clutch member rotates with the gear-wheelwhich is beveled in a direction the reverse of that of the gear-wheel.

chine comes to a stop. To prevent breakage of the chains 30, caused bysudden jerks due to the trips suddenly striking the reversinglevers, Iincorporate within the length of each chain a coil-spring 43, which isof suificient strength and tension to cause the rockingof the shaft 9when the levers are depressed, but which willgive sufficiently when thelevers are struck by the trips to prevent damage to the chains.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, operation, and advantages of myinvention will be readily understood Without requiring a more extendedexplanation.

Various changes in the form, proportion, and details of construction maybe made within the scope of the invention without departing from thespirit or sacrificing any of the advantages thereof.

Having thus described my invention, what I claim, and desire to secureby Letters Patcut, is
